Radio frequency electromagnetic fields of mobile phones and health

Introduction

In many places, mobile phones are an integral part of modern communication. This technique relies on radio frequency signals to pass, radio frequency electromagnetic fields (hereinafter referred to as "radio frequency electromagnetic fields") cause the transmission of the signal.

Are there health effects?

Mobile phone technology produced by the "radio frequency electromagnetic fields," a belonging to non-ionizing radiation, and X-rays, nuclear radiation, ionizing radiation is not the same. In simple terms, non-ionizing radiation energy is low, not enough to change the chemical nature of the substance, the body can not break chemical bonds harm.


Now established and touch "radio frequency electromagnetic fields," the main health effects are associated with thermal effects related. Mobile phones produced by the "radio frequency electromagnetic fields" could be absorbed by the body, and produce a small amount of heat. Because the body's normal body temperature regulation function can eliminate this heat, so now there is no sufficient evidence that the normal use of mobile phones in the next, will lead to adverse health effects.

In 2000, World Health Organization Nucleation IARC launched an international study (INTERPHONE study), in order to understand whether the use of mobile phones and brain tumors. In 2010, the study concluded that: overall, the relationship between mobile phone use and brain tumors, and can not be established between. There are views that the long-term high volume of calls may increase the risk of brain cancer, but studies may bias and error that can not be made to clarify causality. Long-term high-volume mobile phone and possible impacts need further study. In 2011, IARC after a rigorous demonstration, the "radio frequency electromagnetic fields" are classified as "possibly carcinogenic to humans". In general, this category means that not enough evidence in animal experiments, in human terms only limited evidence that may be carcinogenic. In fact, many see the media everyday life also belong to category 2B assessment, such as coffee, some dry cleaners, etc., proved far less than the risk of asbestos, smoking, secondhand smoke, nicotine, ionizing radiation. Long-term high-volume study of mobile phone use will still lead to further brain tumors.

Reduce the risk

While the impact of mobile phones on health still waiting for the results of future studies confirm that we can take some precautions to minimize the contact of mobile phones' radio frequency electromagnetic fields, "such as avoiding long calls and use of hands-free devices and telephones to increase the distance. Members of the public may be particularly concerned about children and adolescents are more vulnerable to radio frequency electromagnetic fields, because they have always had access to such technologies. As a precaution, the child of a non-essential calls should be avoided.
